Description

Technical Field

[0001] The invention relates to the technical field of water electrolysis hydrogen production, and in particular to an energy-saving and carbon-reducing water electrolysis hydrogen production system. Background Art

[0002] Hydrogen production by water electrolysis is a relatively convenient method for producing hydrogen. Direct current is passed into an electrolytic cell filled with electrolyte, and water molecules undergo electrochemical reactions on the electrodes, decomposing into hydrogen and oxygen. Existing water electrolysis hydrogen production devices have certain drawbacks when producing hydrogen. The generated hydrogen and oxygen are easily mixed in the electrolytic box, and the timely storage of hydrogen and oxygen cannot be guaranteed; and the bottom of the electrolytic box is prone to scale after long-term use, which is inconvenient to remove. The scale will greatly affect the efficiency of hydrogen production, thereby increasing power consumption.

[0003] The Chinese patent number is 202321690120.X, which discloses "a device for producing hydrogen by electrolysis of water", including a glass barrel, a glass tube; as well as a float, a convex ring, a magnet ring, a top shell, and a buzzer. By adding a liquid level reminder structure, the operator is reminded to replenish pure water in this way; and the hydrogen and oxygen produced by electrolysis are discharged through two exhaust pipes so that the produced hydrogen and oxygen will not be mixed. The above-mentioned device for producing hydrogen by electrolysis of water can solve the problem of mixing of hydrogen and oxygen. Pure water is used for electrolysis, and basically no scale is generated, but the cost of pure water is high, which is not conducive to cost saving. In the process of water electrolysis to produce hydrogen using soft water, seawater, etc., scale will be generated after long-term electrolysis, and the long-term accumulation of scale will affect the subsequent hydrogen production efficiency.

[0034] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0035] In view of the problems existing in the prior art, the embodiments of the present invention provide an energy-saving and carbon-reducing water electrolysis hydrogen production system, such as Figure 1 As shown, the energy-saving and carbon-reducing electrolytic water hydrogen production system includes a hydrogen production box 1, and a liquid inlet pipe 2 and a liquid outlet pipe 3 respectively connected to the top plate and the side plate of the hydrogen production box 1, N bottom scraper assemblies 5 are slidably arranged on the bottom plate of the hydrogen production box 1, and M side scrapers 4 are slidably arranged on the side wall of the hydrogen production box 1, wherein N is a positive integer greater than or equal to 1, and M is a positive integer greater than or equal to 1.

[0036] In this embodiment, the bottom scraper assembly 5 is provided to scrape off the scale deposited on the bottom of the hydrogen production box 1, and the side scraper 4 is provided to scrape off the scale deposited on the side wall of the hydrogen production box 1. And the scraping process of the combined structure of the side scraper 4 and the bottom scraper assembly 5 can be carried out synchronously with the hydrogen production process, so as to ensure the high efficiency performance of scraping off the scale. In the actual setting, the number of the side scrapers 4 and the number of the bottom scraper assemblies 5 are matched. It can be understood that when the number of the side scrapers 4 is set to one, the number of the bottom scraper assemblies 5 is also set to one; and the end of the bottom scraper assembly 5 away from the vertical center line of the hydrogen production box 1 is arranged to fit the bottom of the side scraper 4, so that the scale scraped by the bottom scraper assembly 5 can pass through the bottom of the side scraper 4.

[0037] In one embodiment, if Figure 3 As shown, the bottom scraper assembly 5 includes a bottom scraper body 51, and an inclined surface 52 and a guide surface 53 arranged on the bottom scraper body 51, wherein the width of the bottom scraper body 51 gradually decreases from the vertical center line of the hydrogen production box 1 to both ends, and forms the inclined surface 52, the bottom scraper body 51 is arranged along the radial direction of the hydrogen production box 1, and the end of the bottom scraper body 51 away from the vertical center line of the hydrogen production box 1 forms the guide surface 53, and the guide surface 53 is matched with the lower end of the side scraper 4.

[0038] The arrangement of this embodiment can achieve a better effect of scraping off scale. At the same time, after scraping off the scale, the scale is guided to the guide surface 53 under the guidance of the inclined surface 52, and then accumulates on the guide surface 53 and jumps to the lower end of the side scraper 4.

[0039] In one embodiment, if Figure 1 and Figure 2 As shown, the energy-saving and carbon-reducing water electrolysis hydrogen production system also includes a connecting mechanism 6, which includes a first connecting column 61, the N bottom scraper assemblies 5 are all fixedly arranged on the lower end side wall of the first connecting column 61, and a horizontal connecting plate 62 is fixedly arranged on the upper end of the first connecting column 61. The M side scrapers 4 are all fixedly arranged on the lower end surface of the horizontal connecting plate 62, and the upper end of the first connecting column 61 is fixedly connected to the second connecting column 63, and the upper end of the second connecting column 63 is rotatably arranged on the inner top wall of the hydrogen production box 1.

[0040] The connection mechanism 6 in this embodiment is used to connect the side scraper 4 and the bottom scraper assembly 5, and through the setting of the connection mechanism 6, the combined structure of the side scraper 4 and the bottom scraper assembly 5 can be rotated synchronously or the combined structure of the side scraper 4 and the bottom scraper assembly 5 can be driven synchronously through the connection mechanism 6.

[0041] When the combined structure of the driving side scraper 4 and the bottom scraper assembly 5 moves, in order to achieve the effect of energy saving and carbon reduction, in one embodiment, as Figure 1 and Figure 2 As shown, the energy-saving and carbon-reducing water electrolysis hydrogen production system also includes a first driving mechanism 7, which includes a first bevel gear 71 fixedly sleeved outside the second connecting column 63, and a second bevel gear 72 meshing with the first bevel gear 71, the second bevel gear 72 is fixedly sleeved outside the first rotating rod 73, the first rotating rod 73 is rotatably set on the inner side wall of the hydrogen production box 1, and a third bevel gear 74 is fixedly sleeved outside the first rotating rod 73, the third bevel gear 74 is meshed with the fourth bevel gear 75, and the fourth bevel gear 75 is meshed with each other. A fixed sleeve is arranged outside the second rotating rod 76, and the second rotating rod 76 is fixedly connected to the third rotating rod 77, and the third rotating rod 77 is rotatably arranged on the inner wall of the hydrogen production box 1. A rotating disk 78 is fixedly arranged outside the third rotating rod 77, and the rotating disk 78 is rotatably arranged in a supporting box 79, and the supporting box 79 is fixedly arranged in the hydrogen production box 1. A plurality of inclined grooves 710 are opened on the circumference of the rotating disk 78, and the upper end of the supporting box 79 is connected to the liquid inlet pipe 2, and a liquid discharge port 711 is arranged on the lower end of the supporting box 79.

[0042] The arrangement of the first driving mechanism 7 in this embodiment can drive the combined structure of the side scraper 4 and the bottom scraper assembly 5 without an external power source, thereby achieving the effect of energy saving and carbon reduction, thereby also reducing production costs; and the power source for the movement of the first driving mechanism 7 is provided by the input liquid, so that the driving of the side scraper 4 and the bottom scraper assembly 5 by the first driving mechanism 7 can be carried out synchronously with the hydrogen production process. It can also be understood that as long as the hydrogen production process is started, the combined structure of the side scraper 4 and the bottom scraper assembly 5 is driven to move for scraping off scale. Specifically, when the liquid is input into the support box 79 through the liquid inlet pipe 2, it will be filled into the inclined groove 710. Since the inclined groove 710 is set at an angle, it will drive the rotating disk 78 to rotate counterclockwise. The rotation of the rotating disk 78 will drive the fourth bevel gear 75 to rotate through the second rotating rod 76 and the third rotating rod 77. The rotation of the fourth bevel gear 75 will drive the combined structure of the first connecting column 61, the horizontal connecting plate 62 and the second connecting column 63 through the combined structure of the third bevel gear 74, the first rotating rod 73, the second bevel gear 72 and the first bevel gear 71, thereby driving the combined structure of the side scraper 4 and the bottom scraper assembly 5 to rotate. It can be seen that in this embodiment, the rotation of the combined structure of the side scraper 4 and the bottom scraper assembly 5 is provided by the hydrogen-producing liquid, and no external power source is required, thereby achieving the effect of energy saving and carbon reduction.

[0043] In order to be able to timely transport the scraped scale to the outside, in one embodiment, Figure 4 As shown, the energy-saving and carbon-reducing electrolytic water hydrogen production system also includes a fixed extraction mechanism 8, which includes an extraction chamber 81 opened inside the first connecting column 61 and the second connecting column 63, and a first extraction pipe 82 and a second extraction pipe 83 movably arranged in the extraction chamber 81, the first extraction pipe 82 and the second extraction pipe 83 are connected to each other, and a deposition chamber 84 is provided between the lower end of the first extraction pipe 82 and the bottom wall of the extraction chamber 81, a first extraction channel 85 connected to the extraction chamber 81 is provided inside the horizontal connecting plate 62, a second extraction channel 86 connected to the first extraction channel 85 is provided on the side scraper 4, and a connecting hole for connecting the second extraction channel 86 with the inner cavity of the hydrogen production box 1 is provided on the lower end side wall of the side scraper 4.

[0044] The fixed extraction mechanism 8 in this embodiment can transport the scraped scale to the outside in time, so as to avoid the scraped scale from being deposited in the hydrogen production box 1. During operation, the scale scraped by the side scraper 4 will fall to the lower end of the side scraper 4 under the gravity of the scale itself, and the scale scraped by the bottom scraper assembly 5 will move to the lower end of the side scraper 4 under the guidance of the inclined surface 52 and the guide surface 53; suction is provided at the upper end of the second extraction pipe 83, and under the action of suction, the scale deposited at the lower end of the scraper 4 can be drawn into the extraction chamber 81 through the connecting hole, the second extraction channel 86 and the first extraction channel 85, and deposited in the deposition chamber 84 under the action of gravity, and extracted to the outside through the first extraction pipe 82 and the second extraction pipe 83 under the action of suction.

[0045] Since the scale contains water in the process of extraction, in order to achieve solid-liquid separation of the scale entering the first extraction pipe 82, in one embodiment, as Figure 5 As shown, the energy-saving and carbon-reducing water electrolysis hydrogen production system also includes a second driving mechanism 9, which includes a fifth bevel gear 91 fixedly sleeved outside the second connecting column 63, and the fifth bevel gear 91 and the sixth bevel gear 92 are meshed with each other. The sixth bevel gear 92 is fixedly sleeved outside the third rotating rod 93, and the third rotating rod 93 is rotatably set on the inner side wall of the sealing barrel 94. The sealing barrel 94 is fixedly inserted on the top plate of the hydrogen production box 1, and the sealing barrel 94 is movably sleeved outside the second extraction pipe 83. The second extraction pipe 83 is fixedly sleeved with a seventh bevel gear 95, and the seventh bevel gear 95 and the sixth bevel gear 92 are meshed with each other.

[0046] The second drive mechanism 9 in this embodiment can make the combined structure of the first extraction pipe 82 and the second extraction pipe 83 rotate relative to the second connecting column 63. In this way, during the rotation process, due to the different masses of the solid and liquid in the scale, the solid and liquid can be easily separated under the action of centrifugal force. When working, when the second connecting column 63 rotates, it will rotate with the fifth bevel gear 91. The rotation of the fifth bevel gear 91 will rotate the second extraction pipe 83 through the sixth bevel gear 92 and the seventh bevel gear 95. The rotation of the second extraction pipe 83 will also rotate with the first extraction pipe 82. In actual settings, the size of the fifth bevel gear 91, the sixth bevel gear 92 and the seventh bevel gear 95 are not consistent. Under the premise of inconsistent size, the second connecting column 63 driven by the first extraction pipe 82 and the second extraction pipe 83 are also inconsistent in speed, so that the first extraction pipe 82 and the second extraction pipe 83 can rotate relative to the second connecting column 63.

[0047] In order to achieve better solid-liquid separation, in one embodiment, as Figure 6 As shown, the energy-saving and carbon-reducing water electrolysis hydrogen production system also includes a plurality of solid-liquid separation mechanisms 10 arranged in the first extraction pipe 82, and the plurality of solid-liquid separation mechanisms 10 are arranged on the same vertical line. The solid-liquid separation mechanism 10 includes a straight pipe section 101, and an arc section 102 connected to the lower end of the straight pipe section 101, the lower end of the arc section 102 is fixedly connected to the inner side wall of the first extraction pipe 82, the inner tube wall of the arc section 102 forms an arc surface 103, a liquid accumulation cavity 104 is opened in the arc section 102, and a plurality of liquid inlet holes 105 connecting the liquid accumulation cavity 104 and the inner cavity of the first extraction pipe 82 are arranged on the arc surface 103, and the aperture size of the liquid inlet hole 105 is less than 0.5 mm.

[0048] The arrangement of the multi-layer solid-liquid separation mechanism 10 in this embodiment can make the scale in the second extraction pipe 83 basically in a dry state. Specifically, when the scale enters the bottom solid-liquid separation mechanism 10, under the simultaneous action of centrifugal force and suction, the scale will move upward along the curved surface 103. During the upward movement, the liquid contained in the scale will enter the liquid accumulation chamber 104 through the very small liquid inlet hole 105, while the larger scale cannot enter the liquid accumulation chamber 104. In this way, with the continuous action of the suction force, the scale after the first drying will enter the penultimate solid-liquid separation mechanism 10 for the second drying. In this way, the arrangement of the multi-layer solid-liquid separation mechanism 10 can make the scale achieve a symmetrical drying effect, thereby ensuring that the scale entering the second extraction pipe 83 is in a dry state.

[0049] In order to achieve better solid-liquid separation effect, in one embodiment, Figure 7 and Figure 8 As shown, it also includes a blocking mechanism 11, which includes a blocking body 111 movably arranged in the straight pipe section 101, and anti-stuck heads 112 fixedly arranged on the upper and lower ends of the blocking body 111, respectively. A guide component 113 is arranged on the side wall of the blocking body 111, wherein the guide component 113 is arranged to guide the blocking body 111 to move only in the vertical direction, and the anti-stuck head 112 is arranged to prevent the blocking body 111 from being stuck when it moves up and down.

[0050] The blocking mechanism 11 in this embodiment can prevent scale from quickly entering the next layer, which can extend the drying time of scale in each layer, thereby achieving a better drying effect.

[0051] In one embodiment, if Figure 8 As shown, the guide assembly 113 includes a fixing seat 1131 fixedly connected to the side wall of the blocking body 111, a guide rod 1132 is fixedly connected to the lower end surface of the fixing seat 1131, the guide rod 1132 is movably inserted in the guide groove 1133, the guide groove 1133 is provided on the straight pipe section 101, the lower end of the guide rod 1132 is fixedly connected to the limited support assembly 1134, the lower end of the limited support assembly 1134 is fixedly connected to the guide groove 1133 On the bottom wall, the limit support assembly 1134 includes a limit support rod 11341, a limit support tube 11342 and a limit support spring 11343. The limit support rod 11341 is movably inserted in the limit support tube 11342, and the limit support spring 11343 is wound around the outside of the limit support rod 11341, and the two ends of the limit support spring 11343 are respectively fixedly connected to the side wall of the limit support rod 11341 and the outer side wall of the limit support tube 11342.

[0052] In this embodiment, the combined structure of the fixed seat 1131, the guide rod 1132 and the guide groove 1133 can play a guiding role, so that the blocking body 111 can only move in the vertical direction; in this embodiment, the setting of the limiting support assembly 1134 can not only play a guiding role for the movement of the blocking body 111, but also provide a reset force for the reset movement of the blocking body 111.

[0053] In one embodiment, if Fig. 9As shown, the energy-saving and carbon-reducing water electrolysis hydrogen production system also includes a liquid extraction mechanism 12, which includes a first main body tube 121, and a second main body tube 123 connected to the first main body tube 121, the second main body tube 123 is arranged in the first extraction tube 82 and the second extraction tube 83, the first main body tube 121 is arranged outside the first extraction tube 82 and the second extraction tube 83, and a connecting tube 122 is fixedly inserted on the first extraction tube 82, one end of the connecting tube 122 is interconnected with the liquid accumulation cavity 104, and the other end of the connecting tube 122 is interconnected with the inner cavity of the first main body tube 121.

[0054] The arrangement of the liquid extraction mechanism 12 in this embodiment can extract the liquid in the liquid accumulation chamber 104 .

[0055] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims.
